IMPROVEMENT l N WATER-WHEELS.

Specification forming part of Letters Patent No. 202,062, dated April2,1878; application filed October 11, 1877.

To all whom it may concern: I

Be it known that I-, CALEB F. SMITH, of Mount Pleasant, in the county ofOabarrus and State of North Carolina, have invented certain new anduseful Improvements in Water-Wheels; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which they appertain to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a waterwheel, as will be hereinafter more fully set forth.

In the annexed drawing, which fully illustrates my invention, Figure ,1is a bottom view. Fig. 2 is a side elevation, and Fig. 3 is a centralvertical section on line 00 00, Fig. 1.

A represents the wheel proper, made cylindrical in form, and formedaround its top with a projecting flange, B, as shown, of the same widthas the buckets O C. These buckets stand at the top nearly vertical, andare then curved forward and extended, as shown at 0,

below the lower edge of the wheel and underneath the adjoining bucket..That portion of each bucket which extends below the wheel and under thenext bucket has its edges I bucket is fastened to the under side of theflange B. A ring, D, also surrounds and connects all the buckets attheir outer edges a suitable distance above the lower edge of the wheel.

By this construction any one or more of the buckets may be removed whennecessary for repairs without taking the whole wheel apart.

The wheel is simple in construction, durable, and is comparativelycheap.

The special advantages of my water-wheel are, that the buckets areattached in such a manner as to receive the water in a straight line,which is the strongest way water can be applied, after which theelongation of the bucket gives full power of the weight of the water inescaping, while the elevation of the outer portion of the lowerextremity of the bucket gives the additional advantage of thecentrifugal force of water in attempting to discharge, thus obtainingall the power there is in the water, due allowance being had forfriction. the water is applied at the extreme radius of the wheel.

This wheel will act as well in eddy-water, because by nature of itsconstruction it will be almost entirely in active water except the lowerextremities of the buckets. It will also waste but little water, asthere is no possible way for its escape except between the ring or bandD and flange B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The within-described water-wheel, consisting of the wheel A, with topflange B, the independently -removable buckets O 0, constructed asdescribed, with concave extensions 0 O, and the surrounding band D, allsubstantially as and for the purposes herein set forth.

Intestimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.
